AWNING-ARM.

Specification of Letters Patent.

Patented Nov. 14, 1916.

' Application filed August 20, 1914. Serial No. 857,751.

To all whom it may concern I Be it known that -we', FREDnRIoK A. MAN- NING and FRANK D. FRAZEE, citizens of the United States, residing at Springfield, in the county of Sangamon and State'of Illinois, have invented new and useful Improvements in Awning-Arms, of which the.

following is a specification.

Our invention relates to improvements in awning arms, and has for its object the provision of a device of that character, which will provide the supporting means for an awning, and which will extend from the front of a building in a substantially parallel relation with the slope of the awning our invention comprises the novel details of construction and arrangement herein'to be described, illustrated in the annexed drawings, and pointed out specifically in the appended claim.

In the accompanying drawings, to which reference will be had, and wherein the preferred embodiment of our invention is illus the like or corresponding parts throughout the several views.

Figure 1 comprises perspective views of our awning arm shown in its working position. Fig. 2 is a side elevation of our assembled arm, also shown in its working relation to an awning cover. Fig. 3 is a top plan view of our assembled arm. Fig. 4: is a sectional view of the spring housing, showing the hinge pin and spring, taken on line H of Fig. 3.

Our awning arm comprises a stationary hanger 1, which is preferably bolted to the wall of the building directly below the awn ing roller 80, and which hanger comprises a projecting vertically disposed disk 2. A

se ond dis 3 is bolted to disk 2 by a pi ting bolt passing through the center of the disks. The adjacent faces of the disks are provided with radial meshing teeth 9, and a nut is provided on bolt 4- whereby' the disks may be locked in meshed relation.

Projecting from disk 3 is a cylindrical spring housing 5, caps 6 being provided on each of the open ends thereof. Disposed above and below caps'6 are parallel lugs 10 and 11, which lugs are provided on the armcarrying yoke 12, each of said lugs being provided with hexagonal perforations therethrough. 7 Numeral 7 designates a hinge pin passing through lugs 10 and 11, caps 6, and cylinder 5. Caps 6 are provided with circular perforations to receive the pin 7 which is cylindrical for the portion of its length between the outer faces of caps 6, hexagonal sectioned portions 13 being provided adjacent each end of the pin where it passes through lugs 10 and 11. One end of pin 7 is provided with a head 7, and'on the other end is disposed a nut 8;

Inside of cylindrical spring housing 5, we provide a coil spring'l l having one end engaged to pin 7 in any suitable manner, as by havlng the end of the spring engaged in a hole 15 in the pin. The other end of the spring is engaged to housing 5 by being inserted in hole 16 in the housing wall.

I Arm-carrying yoke 12 is provided with a projection 12 adapted to receive the upper end of strap iron bar. 18, bolts'being provided to bolt the bar I and projection together. The lower lug 11 of the yoke 12 is hinged to the yoke at 17 such means being provided to allow for the assembling of the device. 7 l

The central hinge comprises a yoke 12, identical in construction to the yoke 12 in the upperhinge, with the exception that the yoke isreversed, the projection 12 being directed inward to engage the outer end of bar 18. Between lugslO and 11 is disposed a cylinder 5, having caps 6 on each end. A hinge pin '7 is passed therethrough and a coil spring 1 1 is disposed about the pin, one end of the spring being engaged to the pin and cent disk. A projection 20 extends outward from disk 2, to which projection the lower strap iron bar 21 is bolted.

The outer end of bar 21 is engaged to front bar 22 of the awning by a hinge, comprising a yoke 23 engaged about the bar 22, and provided with parallel lugs 2 1. The outer end of bar 21 is twisted to enter lugs 24 at right angles to the upper end of that lloar, a hinge bolt 25 pivoting the bar to the ugs. 7

It will be readily understood that the adjustment for pitch provided in our invention comprises the means for adjustment afforded by disks 2 and 3 in the upper and central hinge units. ithe relative relation of disks 2- and 3 may be readily adjusted for a wide range of pitch.

It is to be understood, that while our awning arm may beused in conjunction with aw'mngs'of everyvarlety, yet the necessity of a device otthis general character is experienced, when deslgnl'ng awnings on. store, fronts whereon 1t 1s deslred to have the awn- 7 ing extend at very little pitch. 'In such installations side braces are undesirable, and

J force the upper section .18 upward and around its. pivoting hinge adjacent hanger 1..

(See Fig. 1:) The lower section of arm may be so adjusted for slope as to swing against and above the upper section, the disk3 in the central hinge being slightlyofi'set from cylinder 5 to allow the lower section of arm to lie closely against the'upper section. Both of the sections may thus be adjusted to lie directly under roller 30 in their folded positions. When the awning is lowered,

By loosening the nut on bolt springs 14 will force the arms outward, the springsbeing under their greatest tension when the arms are folded, causing the awning to lower easily and quickly even when adjusted for very little pitch.

In order to prevent the straightening of the arms so that they will not fold when the awning is'rai-sed, we have provided buflfers 18 onthe lower lugs 11' of each of the hinges, which buffers are positioned at a predetermined relation with the disks to prevent complete straightening of the arm. By this means, the front bar 23 cannot be lowered to such an extent that the arms will straighten out sufiiciently to destroy the leverage about each. of the hinge pins.

While we have herein described the pre ferred embodiment of ourinvention, we. do not wish to be limited strictly to the details shown, as it is obvious thatrthe elements of construction and 'arrangement'may be varied in many ways,.without departing from the broad spirit of ourinvention.

. Having thusdescribecl our invention, what we claim is 7 A spring-hinge for connecting the adjacent endsof a pail-of bars, one of the bars having associated therewith a cylindrical with the ends of the pin, and serving to retain the caps on the casing and to permit relative swinging movement of the bars.
